This invention relates .to an improved household power unit, the novelfeatures of which will be best understood from the followin descriptionand the annexed drawings. ln the drawings, I have shown selectedembodiments of the various features forming the invention, and referringthereto; 7

Fig. 8 is a section of the ring only, taken on the line 8-8 of Fig. 7.

I have shown the invention as comprising a movable'base 1 which may beprovided with a plurality of rollers 2 whereby the base and the partssupported thereon may bereadily moved to any desired position when inuse, and may -be easily stored away in an out of the way place when notin use. Extending upwardly from the base is a standard 3 upon whichI'have shown a vertically slidable sleeve 4 supporting a shelf 5 whichmay be rotated about its pivot 6 and secured in any desired position.Suitable handles 7 and 8 are provided forclamping the shelf in such adesired position, in which it may support a container which is to be'used with the unit.

Disposed on top of the standard is a gear casing 9 supporting a motor10. The details of the gearlng in the casing are not shown,

, because they may vary quite widely. It is deemed sufficient to saythat the motor has a shaft 11 upon which is mounted a pu11 ey 12, andthe gearing includes a shaft 13 carrying a pulley 14 which is driven bymeans of a belt running over the two pulleys. By this arrangement thevarious gears and shafts in the casing are given their movement. Thecasing is preferably provided with a plural- 5 1ty of power outlets,each in the form of a rotatable shaft. In this form, I have shown twoshafts 16 and 17 extending from opposite sides of the casing, and eachsurrounded with a shroudso as to protect the shaft and to pre- Ventaccidental engagement thereof by the fingers of the person employing theunit.

Each of the shafts l6 and 17 is provided with a clutch element, asuitable type of, which is shown in Fig. 6 In this figure I have shownas the shaft 16 as provided with oppositely disposed recesses 18 whichform extensions of a central recess in the shaft. Within the centralrecess may be placed a shaft 19 of a device which is to be operated bythe shaft 16, and this shaft 19 is provided with oppositely extendingpins 20 which may be received in the recesscs l8.

operated from the In this form, I have shown hinge members in the formof pins 21 adjacent one outlet,these hinge members being adapted tocooperate with hingemembers 22 on a bracket 23 which can be readilylifted from the hinge pins 21 and can likewise be placed on the pins byvertical movement. The bracket may be releasably held in position bymeans of a spring latch indicated by a pin 23 coacting with an ear 24 onthe bracket. By this arrangement the bracket and any device carriedthereby may be easily swung out of operative engagement with the powerunit, in case of any accident such as catching the operators fingers inany of the moving parts. Adjacent the other power outlet I have shdwnears 25 having apertures therein to receive pins 26 ona ring 27. This 5ring forms another kind of bracket adapted to support other types ofdevices tobe operated from the power unit. It may here be "said that thetwo outlets 16 and 17 will ordinarily be operated at different speeds bysuiti that by this arrangement the bar 31 may be head on the pin 29inthe slot bar 31 and prevents lifting able arrangement of the gearing inthe easin 9.

I will first describe the best shown in Figs. 3 and 4. This bracket ispreferably in the form of the ring 27, and has the pins 26 securedthereto.- It may thus be easily placed in position and removed by asimple vertical movement. If desired, the ring may be provided withinwarly extending lugs 28 to engage a container which may be supportedthereon. Extending upwardly from the ring on opposite sides, are headedpins 29, and the line between these pins is preferably at right anglestoaxis of the shaft 19 on the device supported on the ring. In the formshown, this device is exemplified as a beater 30, this device beingsupported upon a transverse bar 31 which has slots 32 and 33 at itsopposite ends, to receive the pins 29.

It will be noticed that the slot 32 opens towards the casing, while theslot 33 opens towards the end of the bar, or at right angles to the slot32. The slot '33 is deep enough so that when the parts are in operativeposition the pin 29 disposed therein does not touch the bottom of theslot. I have found placed in position by sliding it lengthwise with onepin 29 in the slot 33, and then by rotating it about that pin until-theother pin enters the slot 32 and the clutch elements on the shafts 16and 19 come into engagement. A latch 34 may be provided to aid inholding the bar in position.

The shaft 19 will always be rotated in one direction, which in this caseis counterclockwise, as indicated by the arrow in Fig. 7 The 33 engagesthe of that end of the bar, an action which the rotation of the shafttends to cause. There is also a tend-,

ency to rotation of the bar about the center of the ring, and thisrotation is prevented by the pin 29 in the slot 33 and also by the latch34.

In Figs. 7 and 8 I have shown a different embodiment of the structurejust described, in which the bar 31 is provided with a slot 33 adjacentone end extending in a direction at right angles to the shaft 19 andreceiving a headed pin 29. In this form the bar is provided at its otherend with a hole to snugly receive a headless pin 29. By this arrangementthe head on the pin 29 will prevent the lifting action referred toabove, while rotation about the center of the ringis prevented I by boththe pin 29 and the pin 29.

I will now describe the bracket shown at the left of Fig. 2, thisbracket also being shown in plan in Fig. 5. This bracket is designed tosupport a container such as a pan 35 having a rim 36 of the usual beadedform. On the side of the bracket'adjacent the casing this beaded rim isreceived within grooves 37 in the bracket, and on the opposite side theform of bracket rim is received in forked cars 38. These ears are spacedrelatively close together and mounted between them on a pivot 39 is alatch 40 having a lipadapted to catch under the beaded rim, as plainlyshown in Fig, 2.

The latchis also provided with a'projection I device just describedabove, a container 1s placed with its beaded rim in the grooves 37 andthen the outer portion of the rim 1s swung upwardly be-' 38. The latch40 tween the forks of the ears may be swung away of the rim. The handle44 of course is raised to a substantially'vertical position and then itmay be used to swing the latch on its pivot 39 into and out ofengagement with the rim. The bottom of the lip on the latch is adaptedto permit the rim to force the lip and latch outwardly in a well-knownmanner.

Afer the rim is brought into position, the

be used to bring the latch v with the rim by movement about the pivot39, and then the handle is depressed into engagement with one of thecamsurfaces 45. This will lock the container in position wherein it maybe used to holdany substance which is being acted upon by the handle 44may into engagement to permit this movement 7 device 46. This device inturn is actuated by ashaft' 47 having a clutch 48 adapted to cooperatewith corresponding clutch elements on the shaft 17. The abovearrangement is one which will simpl and easily support the containerwithout de orming the container or its rim.
